Not that it is ideal, but you used to be able to mail order fish half way across the country next day and second day air. Very few places still do this due to regulations, but many fish have been stocked that way over the years. Anyway have to believe with a little care and planning you should be substantially better than bouncing around in a ups truck for 2 days.
This video shows fish stocking using "same day air".
They claim that the fish have a 95% survival rate!
